LEI Adsorbents

Effective, Low-Cost Adsorbent for Removal of Heavy Metals

Adsorbents utilize a patented material to adsorb both forms of arsenic as well as a wide range of contaminants in water. Empty bed contact times as low as 10 seconds achieve high removal efficiencies. The material affords a higher capacity and a lower level of ion interference than Adsorbents utilize a patented material to adsorb both forms of arsenic as well as a wide range of contaminants in water. Empty bed contact times as low as 10 seconds achieve high removal efficiencies. The material affords a higher capacity and a lower level of ion interference than competitive iron and alumina based products.

The media’s absorptive capacity is 7-12 grams of arsenic per kilogram of the adsorbent in drinking water applications with a pH range of 6.5-8.5. Much higher absorptive capacities have been measured, up to 400 g/kg, in industrial treatment applications.
